Sustainable Effluent Treatment in the Ipojuca River: the Power of Electroflocculation With Recycled Aluminum

Objective: This study aims to evaluate the efficiency of electroflocculation using recycled aluminum electrodes for the treatment of effluents from the Ipojuca River, highlighting its potential for environmental sustainability and waste reduction. Theoretical Framework: The research is based on principles of electrochemical treatment and water quality analysis, focusing on parameters such as pH, turbidity, biochemical oxygen demand (BOD), chemical oxygen demand (COD), phosphorus concentration, and the impact of electrode degradation. Method: Experimental tests were conducted using a batch electroflocculation reactor equipped with aluminum electrodes derived from repurposed aluminum cans. Water samples were collected from three distinct points along the Ipojuca River, and physicochemical parameters were analyzed before and after treatment according to environmental regulations. Results and Discussion: The electroflocculation process proved effective in significantly reducing turbidity, phosphorus concentration, and COD, while also improving pH levels. The results demonstrated compliance with environmental standards, confirming the viability of the process for effluent treatment. Additionally, the reuse of aluminum electrodes not only enhanced efficiency but also minimized the environmental impact associated with aluminum waste disposal. Research Implications: This study highlights the potential of electroflocculation as an effective and sustainable alternative for water treatment, offering an innovative approach to mitigate pollution in the Ipojuca River. Originality/Value: By demonstrating the feasibility of using recycled aluminum electrodes in electroflocculation, this study reinforces the importance of sustainable waste management practices and their contribution to reducing environmental contamination.
